24th-Level Monster Conversions

This thread is a continuation of the Monster Project. This thread is for converting old-skool monsters that I feel sit at 24th level. I welcome suggestions on these beasties (or other monster suggestions).

Here is the list of monsters to be converted, along with what I am using as a "primary source":

Very cool. I'm not so good with the monsters, so I don't think I'll add anything. But, if you're taking requests, would you consider doing the juggernaut or the infernal first? Either of them would be awesome to have for my next game session this week.

I was hoping for the Dao and Marid to be in the MM3 also, but alas, it was not to be.

"I usually describe "Record of Lodoss War" as the D&D game you want to run. Whereas Slayers is what actually happens at your table." - Andor

Sooooo obviously I'm still not using the new Monster Builder, as it doesn't yet use MM3 math or export to a useful format. Aargh. Nonetheless...

Well, here's a pdf of my updated-to-MM3 standards dragon turtle, originally appearing in the 11th level list here. A few notes on the changes:

1. Updated the math and (due to its new cracking shell trait) increased its AC by a point.

2. Changed the origin to Fey. It just makes sense to me.

3. Added an aura of hot steam to make it dangerous to approach (it reduces your resist fire by 20) and harder to hit if you don't (if you're outside the aura the dragon turtle gains concealment).

4. Added a weakness to cold- rather than extra damage, you inflict a -2 AC and Fort penalty until the end of the dragon turtle's next turn.

5. Scalding squirt (ugh) becomes scalding spit, and instead of ongoing 5 fire I just made it "and take 10 fire damage at the start of your next turn". By 24th level, a lot of pcs will probably resist that anyway.

6. Scalding blast becomes scalding cloud; other than updating the math, I also changed it from "recharge 5 6" to "recharge when first bloodied".
